Din 2311 2312 2738 Plastic Mold Steel Differences - China

Plastic mold steel is a pearlitic steel grade based on Cr-Ni-Mo, and it is also one of the important materials in the mold manufacturing industry.

Among them, 1.2311, 1.2312 and 1.2738 steel are the most commonly used materials.

Although they are all plastic mold steels, there are certain differences.

This article will discuss the differences between 1.2311, 1.2312, and 1.2738 plastic mold steel from several aspects, so as to help more customers buy suitable steel and better apply it to projects.

2311 vs 1.2312 vs 1.2738 Steel Chemical Composition

DIN 1.2311 plastic mold steel

1.2311 steel is a high strength pre-hardened steel with low carbon content, also widely known as P20 - Its chemical composition is as follows:

Grade-1.2311 DIN 1.2312 plastic mold steel

Compared with other plastic mold steels, 1.2312 steel is the steel with the highest sulfur content, and is also widely known as P20+S steel.

Its chemical composition is as follows:

Grade-1.2312 DIN 1.2738 plastic mold steel

1.2738 steel is an upgraded material based on 1.2311 with nickel added, and is also widely known as P20+Ni steel.

Its chemical composition is as follows:

Grade-1.2738 From the chemical composition of the above three steels, it can be seen that 1.2312 steel is significantly different from the other two steels in terms of silicon and sulfur elements; 1.2311 steel is similar to 1.2738 steel in chemical composition, only the nickel element is different.
